commit r15-11171-g16b2d4fb5505db3055e45ab30e9b3ef23367d66d Author: Torbjörn SVENSSON <[email protected]> Date: Thu Apr 2 19:22:38 2026 +0200 testsuite: scan for case sensitive file extensions in lto.exp On a case insensitive filesystem, like on Windows, the "glob" function in tcl returns an entry for each possible case that matches the expression. For example, `glob -nocomplain -types f -- "foo.{c,C}"` would return both "foo.c" and "foo.C" even if there were only a "foo.c" file in the directory. gcc/testsuite/ChangeLog: * lib/lto.exp: Make file listing case sensitive by doing case sensitive filter after directory listing.
